Sudarshan Chakra, Lord Vishnu's divine discus, is a most potent symbol in Hindu mythology. It is more than a weapon; it symbolizes the eternal institution of religion and instantaneous destruction of unrighteous. This celestial whirling disc, commonly placed in Vishnu's top right hand, is not just a weapon of annihilation, but also a beach of divine order and cosmic equilibrium.
